Internal medicine is the medical specialty dealing with the prevention, diagnosis, and treatment of adult diseases. According to some sources, an emphasis on internal structures is implied.  In North America, specialists in internal medicine are commonly called "internists." Elsewhere, especially in Commonwealth nations, such specialists are often called physicians .  These terms, internist or physician (in the narrow sense, common outside North America), generally exclude practitioners of gynecology and obstetrics, pathology, psychiatry, and especially surgery and its subspecialities.
Trump administration officials have also proposed the establishment of an Emergency Response Fund to respond quickly to emerging public health threats. In the wake of the Ebola and Zika epidemics, . officials have repeatedly called for the need for such a fund. The budget does not provide a specific amount. It says HHS would have “department-wide transfer authority to support the Fund in the case of a natural or man-made disaster or threat.” The fund would be available to receive a transfer of up to one percent of any HHS account, without any limitation on the total, for use in emergency preparedness and response.
